Pork Tenderloin after Bariatric Surgery

I really love cooking with pork tenderloin. It’s such a great change of pace from chicken but it does make enough protein for either the whole family or for leftovers. It’s easy to add a variety of flavors from Pesto Pork Tenderloin to Barbecue to Pork with Apples! I will link several recipes a little further down.

My two biggest tips to tolerate pork after weight loss surgery are to check the internal temperature and remove from heat at 140 degrees F and to take small bites when you enjoy the meal (think a peanut 🥜 ).

Money savings using pork tenderloin

With the inflation of our current times, meat prices have certainly gone up. According to US Bureau of Labor and Statistic (dated April 2022) the increase in pork prices was less than chicken or beef. (Source)

Depending on where you purchase your pork tenderloin, you may notice two in one package. Sometimes I flavor each one differently and cook them at the same time but have a different pork flavor the next evening without cooking again!
